LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 343,578, dated June 15,1886.

Application filed June 15,1885. Serial No. 1665753. (No model.)

Figure lis a vertical longitudial section of my improved shuttle, thespindle being represented as closed, expanded, and locked; and Fig. 2 alike View, the spindle being represented as opened, collapsed,and-locked. In

each of said views a portion of the body of the shuttle is representedas broken off.

Corresponding letters of reference indicate corresponding parts in thedifferent figures of the drawings.

My invention relates to that class of loomshuttles which are providedwith means for securing the cop or bobbin on the spindle when thespindleis closed; and it consists in a novel construction and-arrangement ofthe parts, as hereinafter more fully set forth and claimed, the objectbeing to provide asimpler, cheaper, and more effective device of thischaracter than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation, itsextreme simplicity rendering an elaborate description unnecessary. I

In the drawings, A represents the body 0 the shuttle; B, the spindle,and O the rollerspring. The spindle is pivoted at t in the body A andprovided on its upper side with v the spring D, the outer end of saidspring being welded to the spindle to form the point x, and the innerend fitted to work in a socket, o, in the shank f. A hole, 2:, less indiameter than the socket 12, extends from thebottom of said socketthrough the end of the shank f, and

fitted to work in said hole there is a push-pin,

m, provided with a head, i, to prevent its escape from the hole, saidhead bearing upon the end of the spring D. A friction-roller, E, isjournaled in the outer or free end of the spring .O,said spring beingcurved upwardly,provided jection, a, is formed in the body of theshuttle,

on which the shank f rests when the spindle is closed, a shoulder, 9,serving to stop the spindle when it is opened.

In the use of my improvement the spindle is opened, as shown in Fig. 2,to receive the cop or bobbin, thereby causing the roller Eto pass out ofor be removed from thecavitybin the shank f, and permitting the spring Dto straighten out and force the pin m outwardly through the hole znntilits head i rests on the bottom of the socket c. When the spring Dstraightens out, as described, its body dapproaches the spindle proper,B, or the spindle considered as a whole collapses, thereby enabling itto be inserted in the cop or bobbin. After the cop or bobbin has beenplaced on the spindle and properly adj usted,the spindle is closed orbrought into parallelism with the body A, thereby causing the roller Eto roll into the cavity 2) in the end of the shank f, forcing thepush-pin m against the end of the spring D in the socket o, bending orbowing said spring,and securing the cop or bobbin on the spindle in amanner which will be readily obvious without a more explicitdescription.

It will also be obvious that when the spindle is closed, as described,it will be locked in that position by the roller E and spring 0, theroller being forced into the cavity 1) in the end of the shank f by saidspring; also, that when it is opened it will be'locked by the spring 0and roller E, the end of the shank f resting on said roller or on thespring 0 near said roller, as shown in Fig. 2. V The spring 0, beingconstructed with the slot r,1nay be adjusted on the screw h .to exertany desired degree of pressure on the spindle B.

I am aware that shuttle-spindleshave heretofore been held in open orclosed position by means of springs adapted to bear upon differrentfaces of the shanks of the spindles, according as said spindles were inopen or closed position, and have therefore made no broad claim to suchfeature. I

I am also aware that a shuttle has beenconstructed in which the spindlewas provided with a spring secured thereto at its outer end and itsinner beveled end resting in a socket in the spindleshank, a beveled-faced pin working in a hole in said shank at right angles to saidsocket, and adapted to bear upon the beveled end of said spring,and aspring for bearing upon the other end of said pin; butin the presentinvention the pin is in line with the spring of the spindle and providedwith a head,to prevent its accidental displacement or loss.

Having thus explained my invention, what I claim is- 1. The shuttle-bodyA and the spindle B, pivoted therein, said spindle being provided withthe socket 'u in its shank, and the hole a in line with said socket andextending through said shank,the spring D, having its outer end securedto said spindle and its inner end resting in said socket, and thepush-pin m, having its inner end bearing against the end of said spring,and its body working in said hole, in combination with a spring having aroller adapted to bear against the outer end of said push-pin when thespindle is closed, substantially as described.

2. The shuttle-body A and the spindle B, pivoted therein, said spindlebeing provided with the socket v in its shank, and the hole 2 in linewith but smaller than said socket, and

extending through saidshank, the spring D,

hav ingitsoutcr end secured to said spindle and its inner end resting insaid socket, and the headed push-pin in, having itshead bearing againstthe end of said spring and its body working in said hole, in combinationwith a spring having a roller adapted to bear against the outer end ofsaid push-pin when thespi-ndle is closed, substantially as described. 3.The shuttle body A, the spindle B, pivoted therein, said spindle beingprovided with the socket '0 in its shank, with the hole z in line withbut smaller than said socket and 45 extending through said shank, andwith the cavity 1) in the end of said shank, the spring D, having itsouter end secured to said spindle and its inner end resting in saidsocket, and the headed push-pin m, having its head bearing against theend of said spring and its body working in said hole, in combinationwith the spring 0, secured to said shuttle-body A and provided with alongitudinal slot in its body.thescrew h, for rendering said spring adjustal'le longitudinally of the shuttle-bod y, and the roller E, pivotedin the free end of said spring, said roller being forced by said springinto the cavity 1) and against said push-pin min the spindle-shank whenthe 60 spindle is closed, substantially as described.
